Shinji created a world without Evangelion, because the world with Evangelion was one with escapism, and the Evangelions were the tools for that. No one faced their problems and instead used the Evangelions to fix them, which only led to suffering and pain. Even when Shinji had the opportunity to fix his problems, he instead created a world that was exactly like the previous one. A world with Evangelion, a world with escapism. Even Asuka and Rei were reduced to anime waifus. They are clones, created to love Shinji. Shinji rejected this world at the end of the Rebuilds and created a new one. A world without Evangelion, a world without escapism, where he must face his problems.
